So it is not the problem during data collecting. You are working on 64bit OS but all samples dropped in 32bit modules, and PTU can't interpret them...that was why it said
You may try command line to verify:
1. vtssrun.exe log -ec "CPU_CLK_UNHALTED.CORE":sa=200000 -- app ; log subdirectory will generated
2. vtssview log --convert
3. vtssview log -hot-stack ; can you see samples in expected module?
My opinion is to recompile your program in 64bit mode, so the problem will be disappeared.
Sampling collector options are incorrect; collection cannot continue.
Please try again.

I did a quick test of profiling 32-bit notepad.exe and 64-bit notepad.exe. With the 32-bit version of notepad I got 258 samples in
So, it looks like it really is true that there is no support for 32-bit processes on 64-bit Windows. Given that all sensible developers use 64-bit Windows that is roughly the same as saying that there is no support for profiling 32-bit processes.
Wow. I mean, wow. That's a huge gaping hole. And, this gaping hole in the capabilities of PTU does not appear to be documented, meaning that I wasted several hours trying to get it to work.
The user (of PTU) might discuss issues or new feature requests on this forum - http://software.intel.com/en-us/forums/intel-performance-tuning-utility/
Note that PTU isAlpha (experimental) product only,I recommend to use VTuneAmplifier XE 2011.
